Description

Technical Field

[0001] The present invention relates to a spraying device, in particular to a glass anti-fingerprint liquid spraying device and process, belonging to the technical field of glass processing. Background Art

[0002] A glass anti-fingerprint liquid spraying device is a device used to evenly spray an anti-fingerprint coating on the surface of glass. This device is widely used in the anti-fingerprint coating treatment of products such as mobile phone screens, touch screens, and glass panels, improving the stain resistance and usage experience of glass.

[0003] Ordinary spraying devices usually can only spray one side of the glass. If the bottom surface needs to be sprayed, the glass must be manually or flipped through an additional mechanical device, resulting in additional processes. The glass flipping process requires pausing the spraying, increasing the production time and reducing the production efficiency, especially significantly affecting large-scale production, and increasing the complexity of manual intervention. Therefore, there is an urgent need for a glass anti-fingerprint liquid spraying device and process.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a glass anti-fingerprint liquid spraying device and process.

[0006] To achieve the above purpose, the present invention proposes a glass anti-fingerprint liquid spraying device and process, including a support base.

[0007] An interleaved double-sided spraying mechanism is arranged at the middle position of the top end of the support base.

[0008] The interleaved double-sided spraying mechanism includes two cross-slot slide rails fixedly arranged on the support base. The vertical and horizontal slide slots of the two cross-slot slide rails are symmetrically slid with a first slide way and a second slide way respectively. The inner sides of the two first slide ways are fixedly connected to both sides of the top frame. The inner sides of the two second slide ways are fixedly connected to one ends of both sides of the bottom frame. The outer sides of each adjacent first slide way and the outer sides of the second slide way are rotatably connected to the top and bottom of the inner side of the corresponding rotating rod. First gears are rotatably arranged at the middle positions of the outer sides of the two rotating rods. A spraying direction conversion mechanism is arranged on the top frame. A glass clamping mechanism is arranged on the bottom frame. Driving mechanisms are arranged on both sides of the top end of the support base.

[0009] In one example, the spraying direction conversion mechanism includes a U-shaped frame fixedly arranged on one side of the top of the top frame. Two parallel slide bars are fixedly arranged at the top of the U-shaped frame. The two slide bars are inserted and connected with a slide seat box. A back plate is fixedly arranged on the back of the U-shaped frame. An extending track groove is opened on the back plate. An L-shaped support plate is fixedly arranged on the back of the slide seat box. A rotating shaft is rotatably arranged inside the slide seat box. One end of the rotating shaft is rotatably connected with one side of the inner wall of the L-shaped support plate. A second gear is sleeved on the outer wall of the rotating shaft and placed inside the L-shaped support plate. A side frame is fixedly arranged at the middle position on one side of the back plate. A rack is fixedly arranged on one side of the side frame. The second gear meshes with the rack. The other end of the rotating shaft is fixedly provided with a liquid pipeline. A plurality of spraying nozzles are arranged on the liquid pipeline. An electric hydraulic cylinder is fixedly arranged on one side of the bottom of the top frame. The telescopic end of the electric hydraulic cylinder is fixedly connected with the middle position of the bottom of the slide seat box.

[0010] In one example, the glass clamping mechanism includes a glass through groove opened on one side of the bottom frame. A glass limiting groove is opened on one side of the inner wall of the bottom frame. Two limiting studs are threadedly connected to the tops of the inner walls of the glass through groove and the glass limiting groove. A knob is fixedly arranged at the top of each limiting stud. A rubber limiting pad is fixedly arranged at the bottom of each limiting stud.

[0011] In one example, the driving mechanism includes two symmetrically fixed shaft seats arranged on both sides of the top of the support base. U-shaped support frames are fixedly arranged at positions close to the corresponding shaft seats on the top of the support base. Middle seats are fixedly arranged at the middle positions of the tops of the two U-shaped support frames. Central shafts are rotatably arranged inside the two middle seats. The inner walls of the two shaft seats are rotatably connected to both ends of the transmission shaft. First belt pulleys are sleeved on both sides of the outer walls of the two transmission shafts. The two first belt pulleys are respectively connected to corresponding second belt pulleys through corresponding conveyor belts. The two second belt pulleys are fixedly connected to one end of the corresponding central shaft. Third gears are fixedly arranged at the other ends of the two central shafts. The two third gears mesh with the corresponding first gears.

[0012] In one example, a driving motor is fixedly arranged at one end of the support base. The output end of the driving motor is fixedly connected to one end of the transmission shaft.

[0013] In one example, a roller coating mechanism is arranged between the two cross through groove slide rails:

[0014] The roller coating mechanism includes an extension plate fixedly arranged at one end of one of the cross-channel slides. Seat side plates are fixedly arranged at the top and bottom ends of the extension plate and at the top and bottom ends of the other cross-channel slide. Two strip-shaped chutes are symmetrically formed in the side walls of the two seat side plates. A through rod is fixedly arranged inside each strip-shaped chute. An L-shaped buffer block is inserted through each through rod. Both sides of each through rod are slidably connected to both sides of the inner wall of the corresponding strip-shaped chute. The top of the inner walls of every two symmetrically arranged L-shaped buffer blocks is rotatably connected to both ends of the corresponding roller. A spring is sleeved on the outer wall of each through rod.

[0015] In one example, a switch panel is fixedly arranged on one side of the support base. A drive motor switch and an electric hydraulic cylinder switch are respectively fixedly arranged on the surface of the switch panel. The drive motor and the electric hydraulic cylinder are respectively electrically connected to an external power supply through the drive motor switch and the electric hydraulic cylinder switch.

[0016] The glass anti-fingerprint liquid spraying device and process proposed by the present invention can bring the following beneficial effects:

[0017] [[ID=,9]]Through two cross-channel slides of the present invention, the clamping mechanism for placing the glass can reciprocate horizontally on the cross-channel slides. A spraying direction conversion mechanism is arranged in the vertical direction of the cross-channel slides. Multiple spraying nozzles are first placed above the glass to be sprayed. Since the glass moves horizontally, the upper surface of the glass can be sprayed. Then, as the glass clamping mechanism moves horizontally, the multiple spraying nozzles move downward, and at the same time, the nozzle direction of the spraying nozzles is changed by 180 degrees to spray the bottom of the glass. After the upper surface of the glass is sprayed, the nozzles move downward and rotate 180° while moving with the clamping mechanism to directly spray the bottom of the glass, avoiding the need for an additional step of flipping the glass in the traditional method. The whole process does not require manual intervention and can complete the spraying of the upper and lower surfaces of the glass at one time, reducing pauses and improving the spraying efficiency.

[0044] A roller smearing mechanism 6 is provided between the two cross-groove slide rails 201:

[0045] The roller coating mechanism 6 includes an extension plate 601 fixedly arranged at one end of one of the cross-channel slides 201. At the top and bottom of the extension plate 601 and at the top and bottom of the other cross-channel slide 201, seat side plates 602 are fixedly provided. On the side walls of the two seat side plates 602, two strip-shaped chutes 603 are symmetrically opened. Inside each strip-shaped chute 603, a through rod 604 is fixedly provided. Each through rod 604 is inserted with an L-shaped buffer block 605. On both sides of each through rod 604, it is slidably connected to both sides of the inner wall of the corresponding strip-shaped chute 603. At the top of the inner walls of every two symmetrically arranged L-shaped buffer blocks 605, the two ends of the corresponding roller 606 are rotatably connected. On the outer wall of each through rod 604, a spring 607 is sleeved. One end of the spring 607 contacts one end of the L-shaped buffer block 605, and the other end of the spring 607 contacts the strip-shaped chute 603. The spring 607 is in an unloaded state before the glass enters.

[0046] On one side of the support base 1, a switch panel is fixedly provided. On the surface of the switch panel, a driving motor switch and an electric hydraulic cylinder switch are respectively fixedly provided. The driving motor 510 and the electric hydraulic cylinder 313 are respectively electrically connected to an external power supply through the driving motor switch and the electric hydraulic cylinder switch.

[0047] Working principle:

[0048] 1. First, insert the glass into the glass through slot 401 in the glass clamping mechanism 4, and make one side edge of the glass enter the glass limit slot 402. Rotate the knob 404 on the limit screw 403 to press the rubber limit pad 405 inward against both sides of the glass to ensure that the glass is stable and does not shake during the spraying process.

[0049] 2. Initial state: The electric hydraulic cylinder 313 in the spraying direction conversion mechanism 3 is in the initial position, and the sliding seat box 303 is located at the top of the top frame 204; multiple spraying nozzles 312 on the liquid pipeline 311 are facing the upper surface of the glass; the spring 607 in the roller coating mechanism 6 is in an unloaded state, and the roller 606 has not yet contacted the glass.

[0050] 3. Upper surface of the sprayed glass: After turning on the switch of the drive motor, when the drive motor 510 starts, it drives the transmission shaft 505 to rotate. The first pulley 506 on the transmission shaft 505 drives the second pulley 508 to rotate through the conveyor belt 507, and then makes the central shaft 504 rotate. Since the two central shafts 504 are fixedly connected to the corresponding third gears 509, and the third gears 509 are engaged with the first gears 206, the first gears 206 start to rotate around the third gears 509. At this time, the two first sliding rails 202 move downward, and at the same time drive the glass on the top frame 204 to move downward. Since the two ends of the two rotating rods 207 are respectively rotatably connected to the corresponding first sliding rails 202 and second sliding rails 203, the two second sliding rails 203 drive the bottom frame 205 to move horizontally to the left. The fingerprint liquid enters the liquid pipeline 311 from the external hose and is evenly sprayed on the upper surface of the glass by a plurality of spraying nozzles 312;

[0051] 4. Lower surface of the sprayed glass: The first gear 206 gradually rotates counterclockwise towards the third gear 509. Therefore, it drives the top frame 204 to move downward along the lower part of the vertical chute of the cross-through groove slide rail 201. When the first gear 206 rotates past the 9 o'clock direction of the third gear 509, at this time, the bottom frame 205 moves to the right of the horizontal chute of the cross-through groove slide rail 201. At the same time, turn on the switch of the electric hydraulic cylinder. After the output end of the electric hydraulic cylinder 313 retracts, the sliding seat box 303 moves downward along the sliding rod 302, and the L-shaped frame plate 306 moves downward along the extension track groove 305. When the second gear 308 fixedly sleeved on the outer wall of the rotating shaft 307 contacts the rack 310 on one side of the side frame 309, the liquid pipeline 311 flips 180 degrees, driving the spraying nozzle 312 to flip to the lower part of the glass clamping mechanism 4, and the spraying nozzle 312 sprays upward on the bottom surface of the glass;

[0052] 5. The bottom frame 205 continues to move along the horizontal chute of the cross-through groove slide rail 201. When the glass is about to leave the spraying area, it enters the roller coating mechanism 6. The L-shaped buffer block 605 compresses the spring 607, so that the roller 606 fits the glass surface, evenly coats the anti-fingerprint liquid and removes the excess liquid, improving the coating uniformity;

[0053] 6. The drive motor 510 stops, the glass clamping mechanism 4 returns to the initial position, the knob 404 rotates counterclockwise, loosening the limit stud 403, unlocking the glass, and the operator or the automatic transmission device takes out the glass and transports it to the next process.

9. A glass anti-fingerprint liquid spraying device according to claim 1, wherein: A switch panel is fixedly provided on one side of the support base (1), and a drive motor switch and an electric hydraulic cylinder switch are fixedly provided on the surface of the switch panel, respectively. The drive motor (510) and the electric hydraulic cylinder (313) are electrically connected to an external power supply via the drive motor switch and the electric hydraulic cylinder switch, respectively.

10. The process of a glass anti-fingerprint liquid spraying device according to any one of claims 1-9, characterized in that: The process steps of the glass anti-fingerprint liquid spraying device are as follows: Step 1: First, insert the glass into the glass through groove (401) in the glass clamping mechanism (4), and make one side edge of the glass enter the glass limit groove (402). Rotate the knob (404) on the limit screw (403) to press the rubber limit pad (405) inward against both sides of the glass to ensure that the glass is stable and does not shake during spraying. Step 2: Initial state: The electric hydraulic cylinder (313) in the spraying direction conversion mechanism (3) is in the initial position, and the sliding seat box (303) is located at the top of the top frame (204); multiple spraying nozzles (312) on the liquid pipeline (311) face the upper surface of the glass; the spring (607) in the roller coating mechanism (6) is in an unloaded state, and the roller (606) has not yet contacted the glass. Step 3: Spray the upper surface of the glass: After turning on the drive motor switch, when the drive motor (510) starts, it drives the transmission shaft (505) to rotate. The first pulley (506) on the transmission shaft 505 drives the second pulley (508) to rotate through the conveyor belt (507), and then the middle shaft (504) rotates. Since the two middle shafts 504 are fixedly connected to the corresponding third gears (509), and the third gears (509) are engaged with the first gears (206), the first gears (206) start to rotate around the third gears (509). At this time, the two first sliding rails 202 move downward, and at the same time drive the glass on the top frame (204) to move downward. Since the two ends of the two rotating rods (207) are respectively rotatably connected to the corresponding first sliding rails (202) and second sliding rails (203), the two second sliding rails (203) drive the bottom frame (206) to move horizontally to the left. The anti-fingerprint liquid enters the liquid pipeline (311) from the external hose and is evenly sprayed on the upper surface of the glass by multiple spraying nozzles (312). Step 4: Spray the lower surface of the glass: The first gear (206) gradually rotates counterclockwise towards the third gear (509), so it will drive the top frame (204) to move downward along the lower part of the vertical chute of the cross-through groove slide rail 201. When the first gear (206) rotates past the 9 o'clock direction of the third gear (509), at this time, the bottom frame (205) moves to the right of the horizontal chute of the cross-through groove slide rail (201). At the same time, turn on the electric hydraulic cylinder switch. After the output end of the electric hydraulic cylinder (313) retracts, the sliding seat box (303) moves downward along the sliding rod (302), and the L-shaped frame plate (306) moves downward along the extended track groove (305). When the second gear (308) fixedly sleeved on the outer wall of the rotating shaft (307) contacts the rack (310) on one side of the frame seat (309), the liquid pipeline (311) flips 180 degrees, driving the spraying nozzle (312) to flip to the lower part of the glass clamping mechanism 4, and the spraying nozzle (312) sprays the bottom surface of the glass upward. Step Five: The bottom frame (205) continues to move towards the transverse chute of the cross-shaped through groove slide rail (201). When the glass is about to leave the spraying area, it enters the roller coating mechanism (6). The L-shaped buffer block (605) compresses the spring (607) to make the roller (606) fit the glass surface, evenly coat the anti-fingerprint liquid and remove the excess liquid, improving the coating uniformity. Step Six: The driving motor (510) stops, the glass clamping mechanism (4) returns to the initial position, the knob (404) rotates counterclockwise to loosen the limit stud (403), unlocking the glass. The operator or the automatic transmission device takes out the glass and transports it to the next process.
